在关于固氮基因直接转移到作物中的最新实验表明,感染了杂种细菌的玉米和糖用甜菜能够固氮,其产量比实验室对照高10％～180％。作物遗传国际有限公司在最近的一份欧洲专利申请里申报了这些成果(EPO125 468,Newswatch,2月18日,第4页)。在这份申请里,还对抗菌素的合成细菌杂种和生长调节剂进行了讨论。Peter S.Carlson(该公司的一位科学家和创始人)说,在对固氮感兴趣的
Recent experiments on the direct transfer of nitrogen-fixing genes into crops have shown that corn and sugar beet infected with the hybrid bacteria are able to fix nitrogen, yielding 10% to 180% more yield than laboratory controls. Crop Genetics International Ltd. filed these results in a recent European patent application (EPO 125 468, Newswatch, Feb. 18, p. 4). In this application, antibiotic synthetic bacterial hybrids and growth regulators are also discussed. Peter S. Carlson, a scientist and founder of the company, said that while nitrogen fixation is of interest
